Closed-Loop Model-Based Control Barrier Functions with Application to Robust Flight Envelope Protection
Johannes Autenrieb, Mark Spiller, Peter A. Fisher +3
Ensuring operation of aerospace systems within prescribed flight envelope limits is a fundamental requirement for modern flight control architectures. Flight envelope protection ai…
Flight Envelope Protection for a Hypersonic Glide Vehicle Using Adaptive Safety-Critical Control
Johannes Autenrieb, Peter A. Fisher, Anuradha Annaswamy
This paper presents an adaptive safety-critical control framework for flight envelope protection (FEP) of hypersonic glide vehicles (HGVs) under model uncertainty. The proposed arc…
Robust Safety Filters for Lipschitz-Bounded Adaptive Closed-Loop Systems with Structured Uncertainties
Johannes Autenrieb, Peter A. Fisher, Anuradha Annaswamy
Adaptive control provides closed-loop stability and reference tracking for uncertain dynamical systems through online parameter adaptation. These properties alone, however, do not…
Adapt and Stabilize, Then Learn and Optimize: A New Approach to Adaptive LQR
Peter A. Fisher, Anuradha M. Annaswamy
This paper focuses on adaptive control of the discrete-time linear quadratic regulator (adaptive LQR). Recent literature has made significant contributions in proving non-asymptoti…
An Error-Based Safety Buffer for Safe Adaptive Control (Extended Version)
Peter A. Fisher, Johannes Autenrieb, Anuradha M. Annaswamy
We consider the problem of adaptive control of a class of feedback linearizable plants with matched parametric uncertainties whose states are accessible, subject to state constrain…
Safe and Stable Formation Control with Autonomous Multi-Agents Using Adaptive Control (Extended Version)
Jose A. Solano-Castellanos, Peter A. Fisher, Anuradha Annaswamy
This manuscript considers the problem of ensuring stability and safety during formation control with distributed multi-agent systems in the presence of parametric uncertainty in th…
